Using methanolwater(V∶V=1∶1) as extraction solvent, ultrasonic extraction was performed at room temperature, sample extract was cleaned up by solid phase extraction cartridge, separated by a polyvinyl alcohol ion chromatographic column bonded with quaternary ammonium group, and analyzed by diode array detector. The method showed good antiinterference performance, the linear correlation coefficient r>0.999, and the method detection limit of ρAminobenzene sulfonic acid was 0.1 mg/kg, mAminobenzene sulfonic acid was 0.2 mg/kg while oAminobenzene sulfonic acid was 0.2 mg/kg when sample weight was 5 g. The recoveries were 83.5%~99.5%, 83.1%~98.0% and 77.8%~92.5%, respectively. The results of the recovery experiment of soil samples in 5 regions showed that the method has strong applicability and can meet actual needs. %R %U http://www.hjjkyyj.com/hjjkyyj/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
